With 15 years working in financial institutions before my present life I suggest this.
Any place you have credit with can check for you to see if any inquiries have been made. Also, running a credit check for yourself will also show any inquiries.
You've for sure been told a lot, and the notices to the reporting agencies are a required early step.
It will take many months of vigilance, as there is a market for credit info, and many times a checkbook for instance will be sold numerous times.
In general, Credit Unions as places to conduct business have numerous advantages. Beyond saving you significant $, and keeping your money in your own community, they treat you as a member, not a customer. This is reflected in service.
Lastly, while it is fine to give testimonials about how we avoid any credit and live with only cash transactions, many of us don't live with only cash. Credit and such has numerous advantages as well. And it's not much fun kicking anyone who has the blues.
Good Luck.
